On e-bay there is currently 1-46,2-48's and 1 - 52 GMC buses for sale. The one that has peaked
my interest is the 48 closest to Montana. Bad engine (just the start I'm sure)
So the question is what are the dimensions of a 6-71? I have a spare L10 that if possible I might
want to put in.
Probably just dreaming.
Thanks

Hi folks, don't forget the Scenicruiser for sale in WA.
Skip: The 6-71 in a GM bus will be a left turning engine.
Jack,
Can't seem to find it....do you have the link or number?
Oh my that doesn't make good soap :0 Thanks Stan
Skip
the 3751 has a very tight engine compartment. the only way something other than a 6-71 will fit is if it is smaller or exactly the same size.
there are a host of other issues as well that would preclude most from taking on a project like that
Tekebird,
I could go with my J.D. 150 hp. (a little light for what I would want) or go with a JD 210 hp.
but the left hand rotation thing really brings up a quagmire of hurtles. Ag engines are fairly
cheap and easy to work on. My case 501 engine is too big and my cat d333 is really to big.
I seem to always forget about DD engines that do Left hand rotation. I have nothing against
DD but I tend to stick to things I at least know how to rebuild.
Thanks

Hi Maria, here is the link.

Jackhartjr,
I would have never looked under "Collectibles > Transportation > Buses, Taxi Cabs"
So I suppose if nobody can find it will it make minn?
You know you can get it and I will store it for you :)

A 6-71 is 54"L X 29"W X 39"H and weighs 2190 Lbs. (Estimated)
A 6V71 is 41"L X 39"W X 48"H and weighs 2010 Lbs. (Estimated)
By contrast,
a 6V92 is 41"L X 39"W X 47"H and weighs 1960 Lbs. (Estimated)
A 6V92T is 41"L X 39"W X 52"H and weighs 2005 Lbs (Estimated)
Or,
An 8V71 is 47"L X 39"W X 51"H and weighs 2310 Lbs. (Estimated)
A way to get around the LH rotation problem, you could use a ZF transmission out of a Gillig or a Neoplan Transit.
Just being helpful.

Why do they have to have these so far away?
Green-Hornet,
What I told "Jackhartjr" applies for you also. Buy it get it here K buck is their price on delivery.
Plus I promise not to take it to WM to scare the tourists with an air horn in the middle of the night.
Of course before the wind up all the pre buy stuff is advised.

Unfortunately in a 3751/4151, your limiting factors are every direction, Bernhart bus in PA did a repower on a Silversides some time ago...long process and I am sure was into the 25k+ range and had major engineering

Dallas: Does the ZF transmission have the right angle for a bus that old?
The 6-71 and L10 are close in demension, but you'd have to run the L10 with a reverser gear, or switch to a ZF transmission. The only engine swap I've seen on a 3751 is using a Series 50 with a V730 Allison, and was an extremely tight fit. Personally, just rebuilt the 6-71 into a turbo with air to air intercooler, you would go from 220hp and 600lb ft to 300hp and 900lb/ft torque-or 50% more torque! Makes for a good performer. Good Luck, TomC
Stan,
If memory serves ZF makes a couple of diff configs for the 500 series transmissions.(EcoMat) 80 deg left hand and 80 deg right hand.
Ok I looked it up don't trust my own memory.
Dallas thanks. I printed out the dimensions and put it in my bus book for future reference.
TomC
That is always a good option. 900 lb/ft is a remarkable amount.
Tekebird
that is probably where I got the idea to begin with of course I didn't remember the money range. If I remembered the money
and what I have spent on my bus already.........well I just won't go there :)

Stan,
From one ZF I looked at, the configuration was actually an "L" shape instead of being a "V".
The engine was transverse with the transmission in the standard place, then a right angle drive down the passenger side of the coach. The differential yolk was square to the drive and the differential was offset to the right side leaving only about 18" of right hand axle and 50" of left hand axle.
I'll see if I can find the picture that I found of it on the internet.
Dallas
The 3751, 4151 and 4103 are beautiful buses like no others and the 671 is the perfect powerplant for them all.
These buses are so light weight that they don't need more power. They also don't have air bags but owners claim they ride like baby carriages. I love my 4104 but those bags are a pain in the rear-and front.
Get one, keep it stock and you will never be sorry. They have that really neat steering column shifter and the classiest rear engine cover ever designed.!
The 3751/4151s have a major weakness in the Al structure above the rear axle. This will show as a small vertical crack just ahead of the LH rear emergency door. The bus companies came up with a fix that was basically a 7' long steel plate bolted to the original structure.
Make sure any bus you buy has this fix.
no emergency doors on the 3751/4151
I take that back they did....very last window on the Driver's side.
was not aware of the structural issue there.
most of the issues I have seen are every fastener seized up and rusted.
availability of body parts and leses is nill
Dallas: I have never knowingly looked at a ZF transmission in a bus so I asked the question because of the angle change after the 4104. Your description sounds like a rear axle change would be required to use a ZF.

Stan,
In the one I mentioned, yes, it would require an axle change and modification. The nice thing about that,though, is the axle could be any standard "T" drive axle.
The other thing I've found is that ZF makes angle drives for about any configuration. One of the most popular seems to be the 80° for transit coaches.
I looked at a few of ZF offerings at GATS in Lousville, Ky a few years ago, and pretty much they can take any of their transmissions and put about any of their angle drives on them (within reason). This makes a lot more sense to me than Allisons idea of building the angle drive integral to the transmission.
I still haven't found the website where I saw the 90° drive, but I'll look some more tonight.

Very nice offer. Just not ready to Pull the trigger yet.
